Here's yet another case of "Japan gets all the nice things." Earlier today, local carrier au by KDDI announced its smartphone lineup for the summer, and the one that caught our attention was the new HTC J Butterfly (HTV31), which will no doubt be entering other markets as the Butterfly 3. With the centered 13-megapixel selfie camera and subtle front-side BoomSound stereo speakers, this new phone shares a similar face with the Desire Eye and the Desire 826; except its 5.2-inch screen has a much sharper Quad HD resolution. The familiar Duo Camera feature on the back (for bokeh plus filter effects) is here to stay, though for some bizarre reason, the secondary camera is placed below its 20.2-megapixel counterpart instead of above it, meaning you'll have to be more careful with where you place your index finger while holding the phone.

The feature phone. Still big in Japan. Still being sold in the millions. Still relevant, though? And does it even matter what a 30-something tech writer at a Western tech site thinks? Japan's large elderly population -- people who haven't even heard of Angry Birds, Gmail or Uber -- they're the ones sticking to their flip phones. Hardy, easy to use and cheaper than an iPhone. (If you need a primer on the phenomenon of gara-kei, you should probably read up on that here, but in short, it's how Japan's mobile phone market sped ahead with early technologies, then faltered when smartphone competition arrived.) So let's try using one. The best and newest feature phone available in Japan, no less. It's pitched as bringing the best smartphone features to the flip form factor. Is it better than a plain, old smartphone? Good lord, no.

Japanese carrier au by KDDI has been creating tech-as-art for well over a decade with its Infobar line of phones. After starting with a stylish-but-dumb cameraphone in 2003, the brand began offering fully-fledged smartphones with the A01 back in 2011. It's now back with the third iteration of the A series, the A03, and it's as pretty as ever.

Industrial design for the latest Infobar comes from minimalist product designer Naoto Fukasawa, who has worked on the range since its inception, and also created Muji's wall-mounted CD player, part of the MoMA's permanent collection. After the uncharacteristically bland A02, the A03 returns to Infobar's more colorful roots. Encased in anodized aluminum, the A03 has a 4.5-inch 1080p display, 13-megapixel camera, 16GB of storage (expandable with microSD) and capacitive keys for navigation. It's available in a number of hues, but our favorite is undoubtably "nishikigoi," the koi-inspired coloring that Infobar is famous for.

Transparency has always been one of Mozilla's big selling points with Firefox OS, but a new smartphone from KDDI in Japan is taking that idea to its literal extreme. KDDI's Fx0 is the first Firefox OS phone to hit Japan, and as you can see, its clear case (crafted by designer Yoshioka Tokujin) doesn't leave much to the imagination. It's also the first device running Mozilla's mobile platform to include LTE and NFC. And unlike most Firefox OS phones, it packs in some decent hardware, including a quad-core 1.2GHz Snapdragon 400 processor, 1.5GB of RAM, and a 4.7-inch IPS display. Up until now, Firefox OS been targeted at low-end devices for emerging markets like Brazil. But the Fx0 shows that Mozilla wants to take on developed markets, rather than just compete for scraps.Slideshow-254418

The internet is quickest when you have a direct connection to the sites you're trying to reach, but that's a daunting challenge in the Pacific -- undersea network cables can cost hundreds of millions of dollars. It's therefore good to hear that Google and a host of telecom giants (China Mobile, China Telecom, Global Transit, KDDI and SingTel) are backing FASTER, a $300 million fiber optic cable that runs between Japan and the US. As the name implies, it's all about speeding up data transfers between Asia and the Americas; the cable should offer a whopping 60 terabits per second of bandwidth between the two regions, which makes even Google's gigabit home internet service look puny by comparison. You won't see the difference until FASTER is finished in the second quarter of 2016, but it promises to improve the internet as a whole when it's ready. Don't be surprised if foreign multiplayer games and video streams get noticeably smoother within a couple of years.

Japanese carrier KDDI has just announced a new HTC J Butterfly, a handset which resembles the HTC One in specs, but with features aimed at KDDI's home market. Like a lot of other Japanese devices, the 5-inch, full HD handset is waterproof in case you feel like taking fish photos. And to do so, the latest from HTC has brand new cameras: a 13-megapixel rear dual-camera model with a selfie-friendly 5-megapixel front shooter. That differs from the One M8's 4-megapixel Duo "Ultrapixel" camera. KDDI instead calls it a "Duo Effect" camera, with the secondary 2-megapixel module giving depth-of-field adjustment and other features. Filling out the spec sheet are a Snapdragon 801, 802.11ac WiFi, LTE-Advanced, 150Mbps 4g, 2GB of RAM, Android 4.4 KitKat, JBL audio profile (plus bundled earphones) and a Dot View case. All of that sounds pretty nice, but will it come to US shores? Hard to say, but the last J Butterfly model did eventually arrive as the Droid DNA (to Verizon), so we wouldn't be surprised to see the new model here too.

KDDI has just launched the first QuadHD (QHD) phone solely for the Japanese market, the Isai FL model built by LG. That gives us a preview of LG's G3's 5.5-inch 2,560 x 1,440 display and its record 538ppi resolution. As it happens, LG just announced that the panel has now been certified, and re-confirmed that it'll be installed in it's "forthcoming flagship smartphone," ie the G3. KDDI's model may give us an idea of what LG's eagerly-awaited G2 successor will be like spec-wise, too. The Isai FL has the narrow bezels we saw in leaked images of the G3, but sports a different design lacking the LG's rear buttons and rumored metal back. It also has some of LG's Knock functions and will come in three colors with a 13-megapixel camera, 3,000mAh battery, 2GB of RAM and a quad-core Snapdragon 2.5GHz CPU. That lines up with some of the G3's rumored specs, but we won't have to wait long to know them -- it's set to arrive on May 27th.

The Japanese get phone alerts for natural disasters, but they have more than that to worry about these days with an occasionally belligerent North Korea just a stone's throw away. Accordingly, Japan's Fire and Disaster Management Agency says that it will soon warn phone owners when there's a hostile missile launch, a terrorist attack or a similar human-made threat to their region. The new alerts will use the disaster technology from before, so residents won't have to worry about software upgrades when the warning system takes effect on April 1st. Locals hopefully won't ever see the system put to use, but it's good to know that it exists.

Sony's PlayStation Now streaming game service is still months away from launch, but Japanese cable company KDDI is testing the idea with the app-based GameNow service, through cable. It's the same company responsible for LG's Smart TV game service, although judging from the title lineup, J:Com and JCN cable subscribers might not see games at the level of Devil May Cry 4 and Dead Rising 2, at least to start with. Temper that enthusiasm a little, and expect several puzzle games and sports titles, including Pro Evolution Soccer, World Rally Championship 3 and Sonic Adventure DX. KDDI's Smart TV Box launched in 2012, but its new gaming service will go live at the start of March. And hey, know where you could play Sonic over cable, just over 20 years ago? The Sega Channel, that's where.

Dropping its radios for cell service and turning itself into a tablet... The 6.4-inch Xperia Z Ultra may be big enough to pull it off, but are you willing to pay just under $500 (52,000 yen) for the pleasure? Sony hopes you will. It's a Japan-only deal for now (neatly tying in with KDDI's own 4G-capable Z Ultra, also announced today), but we could imagine it filling tablets shelves at your nearest electronics store. If Sony tells us anything more, we'll let you know.

For Fujitsu, fingerprint readers on smartphones are old hat; on Android tablets, however, they're still rare. The company should make those sensors easier to find with its latest Arrows Tab, the FJT21. The 10.1-inch slate uses its fingerprint reader to streamline Android 4.2's multi-user support, signing anyone in with a swipe. Families can also implement both a simple mode for newcomers and a content-restricted kids' mode. Fujitsu isn't leaning solely on sign-in technology to sell its tablet, though. The FJT21 centers on a 2,560 x 1,600 LCD with Gorilla Glass 3 protection; under the hood, there's a fast 2.2GHz Snapdragon 800 processor, an 8-megapixel rear camera, a 1.3-megapixel front camera and 64GB of expandable storage. Japan's KDDI will ship an LTE-equipped version of the new Arrows Tab in late November. Sadly, it's doubtful that we'll see an equivalent model reach the US.

Think 150Mbps LTE-Advanced data is quick? KDDI could offer far more bandwidth next year. Nikkeiclaims that the Japanese carrier plans to upgrade its cellular network to 220 Mbps data as soon as summer 2014. Service would reportedly launch with an Android smartphone, and rely on new wireless technology; it's not clear whether this entails a faster LTE-A variant or something new. KDDI hasn't confirmed the rumor, so we wouldn't consider moving to Japan just yet. If there's any truth to the claims, however, even NTT DoCoMo's upgraded LTE could soon feel downright pokey.

Cramming 13-megapixels into a phone means nothing if you don't have nice optics to boot. Fortunately, Sharp's Serie SHL22 has an unusually fast f/1.9 lens to go with its high-resolution sensor. Launching on KDDI this Friday, this Aquos Phone runs Android 4.2, has a fairly big 3,080mAh battery, a 4.9-inch 720p screen using Sharp's own IGZO technology, Qualcomm's Snapdragon 600 clocked at 1.7GHz, 2GB of RAM and 16GB of internal storage (expandable via microSD). The phone is a bit thicker than what we're used to these days, at 9.9mm (0.39 inches), but we're willing to ignore that if it means leaving our charger at home. Marginally informative video after the break.

These days, the presence of a microSD slot on new handsets is arguably more important than the amount of storage on the inside. One such slot found its way onto the Chinese variants of HTC's One, and now Japanese network KDDI has unveiled its model -- the HTC J One (aka HTL22) -- also with expandable memory on the spec sheet (up to 64GB cards supported). An accompanying promo video has informed us of some new camera modes as well, including a best shot feature like Nokia's Smart Group Shot or BlackBerry's Time Shift, the ability to edit out background photobombers, and creating slow-mo highlights within video clips. We'd hope to see a camera software update bringing these features to US Ones in the future, but for now, check out what you're missing in the video below.

Correction: We originally reported that some of the camera modes shown off in the HTC J One promo video below were new, but commentors have pointed out that these features already exist within the gallery / Zoe UI. The video gives the impression that these features were moved to the camera UI, alongside HDR and panorama (like on the GS4), but that's not the case. A few eyes also spotted there's some extra detail on the back panel below the camera. Fear not -- we're digging.

Update: We've come to the conclusion that the black oblong under the main camera -- similar to the one found on KDDI's J Butterfly variant -- is for IR communications (read: it's different from the power-key emitter). Oh, and that logo under the flash signifies FeliCa NFC-based payment support.

The FCC may have spoiled the surprise, but Sony's now gone official with yet another smartphone and this one's for its native Japan. The Xperia UL appears to be a slightly thicker riff on the Xperia Z, matching the display of the company's early-2013 flagship, with a quad-core 1.5GHz Snapdragon S4 Pro (APQ8064) ticking behind the 5-inch 1080p screen. It's worth noting that it's a substantial resolution bump from the similar-looking 720p NTT DoCoMo Xperia A. Although it's not the Snapdragon 600 rumored, Qualcomm's S4 Pro flexes its muscle through Exmor RS 13-megapixel camera sensor, offering up the ability to capture 15 frames in a second. NFC, naturally, is already in attendance as well as the Felica wireless payment system. You'll also get the benefits of both a physical camera button and water (IPX5/8) and dust resistance (IP5X) -- two features in tandem that should help separate it from Sony's pair ofexisting 5-inch 1080p smartphones. The Xperia UL will launch on KDDI's au network in white, black and hot pink colors on May 25th. Check out the obligatory close-up ad after the break.

Update: The Xperia UL runs on an S4 Pro processor, not the Snapdragon 600 initially stated.

It was only a couple of weeks ago that we got an early peek of T-Mobile's Xperia Z thanks to the FCC, but we've now already gotten word of another unannounced Sony handset. While the published FCC report doesn't offer much more than a label, Blog of Mobile has turned up some images of what's purported to be the Xperia UL (codenamed "Gaga"), giving us an early look at the 5-inch device clearly inspired by other members of the family design-wise. What's more, the UL is allegedly sporting Qualcomm's Snapdragon 600 chip, along with 2GB of RAM, 32GB of built-in storage, a 2,300mAh battery and waterproof / dustproof attributes (these being common Japanese standards). Word on the internet is the Xperia UL will be launching as a KDDI exclusive, though we'll have to wait for something more concrete to see if that's indeed the case. Until then, you can peruse the gallery after the break to get a slight idea of what to expect.Gallery-188598

Sure, it's possible to get remote access to home theater devices through raw methods like a Slingbox, but KDDI has a slightly more elegant solution for those living in Japan. Its tiny Remote TV box puts a Blu-ray DVR on the local WiFi network to both schedule recordings while away and stream the video itself. Locals can watch from a Mac, Windows PC or Android device, although they'll be limited to 480p when they're outside of the home. iOS support is coming soon, the carrier says. KDDI ships the device on February 23rd for an estimated ¥19,800 ($213) and is keen to note that it doesn't require a subscription -- it sees Remote TV more as an incentive to splurge on smartphone data, which just might work for commuters wanting to catch up on their shows.

KDDI's funky au Infobar is back! Once again designed by the famed Naoto Fukasawa, this A02 -- co-developed by HTC -- brings the series up to date with Qualcomm's 1.5GHz quad-core APQ8064 (but with just 1GB of RAM), 4.7-inch 720p display, 16GB of storage, microSD slot, 2,100mAh battery, LTE radio (800/1500) and Android 4.1. Better yet, this phone also supports both CDMA2000 800/2100 and WCDMA 850/1900/2100, making it a great global phone. Judging by one of the demo clips after the break, it seems that this Infobar's 8-megapixel main imager (with F2.0 lens) and 2.1-megapixel front-facing camera take advantage of HTC's ImageSense chip for speedy burst shots. Likewise, you'll find Beats Audio built into the system. As per typical Japanese mobile phone, the usual NFC (with Osaifu-Keitai mobile wallet), 1seg TV tuner and infrared are also packed inside the 9.7mm-thick, 147g-heavy waterproof (IPX5 and IPX7) and dustproof (IP5X) body.

We're already fans of the iconic nishikigoi (meaning "brocaded carp") color scheme as pictured above, but what really caught our attention this time are the fluid animations and uniqueness of the "iida UI" 2.0 (iida stands for "innovation," "imagination," "design" and "art") by interactive designer Yugo Nakamura. As you'll see in the video clips after the break, the home screen here shares some similarities with Windows Phone 8's counterpart -- in the way items snap to grid and resize, even though the former is enhanced by plenty of bouncy animation, more colors and funny sounds (designed by Japanese musician Cornelius). Expect this A02 -- which is also available in blue or gray -- to hit the Japanese market in mid-February.

Its no Droid RAZR Maxx HD, but Kyocera's Digno S just might be the trick longevity lovers in the land of the rising sun are looking for. This 4.7-inch Android 4.0 handset's 2,520mAh battery claims to have the largest capacity of any sub 5-inch device in Japan, promising more than 18 hours of talk time, and between 580 (3G) and 720 (LTE) hours on standby. If that isn't quite enough power for you, you won't have to wait long for a recharge: Kyocera says the Digno S can go from 0 to 50 percent in only half an hour. No word yet on price and availability, but the 1.5GHz dual-core device will be available through KDDI in white, pink and blue at launch. Check out Kyocera's official press release after the break.

We were intrigued by Sony's Xperia V back at IFA, but deals with specific carriers haven't been very forthcoming. Japan's KDDI is covering that gap by pledging to carry Sony's mid-size Android 4.0 phone as the Xperia VL. Everything we know and (mostly) love about the dust- and water-resistant phone is intact, including that thin sensor-on-lens 720p display, the 13-megapixel camera, the 1.5GHz Snapdragon S4, NFC and LTE-based 4G. The one question remaining is a definitive release date: Sony will only promise an Xperia VL launch before the end of the year, although there's talk at Impress Watch of a release on November 2nd for ¥30,000 ($381) after carrier discounts. Let's hope for the company's sake that other carriers sign up for the V and VL sooner rather than later.

The AQUOS Phone Zeta SH-02E was first with Sharp's new IGZO LCD technology a few days ago and it's been followed quickly by another device, the AQUOS Pad SHT21. Scheduled to debut on Japanese carrier KDDI in mid-December, this 7-inch slate claims battery life of up to two and a half times greater than the previous model thanks to the low-power characteristics of its display, and weighs just 280g. It's powered by a 1.5GHz dual-core MSM8960 Snapdragon S4 CPU, and features a 1280x800 screen resolution, pen input, 1GB RAM, 16GB built-in storage, microSDXC slot, Bluetooth 4.0, MHL, NFC, 3,460mAh battery and 4G LTE capability. Hit the source link for more details courtesy of Engadget Japanese.

We've been hearing about a certain 5-inch HTC phablet for Verizon since July, but it looks like its Japanese counterpart may actually hit the market first. Unveiled by KDDI as the HTC J Butterfly (HTL21), this Android 4.1 device is the first announced phone to feature a 5-inch, 440ppi full-HD "Super LCD 3" panel, and it's fittingly complemented by a 1.5GHz quad-core APQ8064 underneath, making this the latest member in the small family of Snapdragon S4 Pro phones. There's an eight-megapixel camera that naturally handles 1080p video at the back, accompanied by a 2.1-megapixel front-facing imager. Other details include 2GB RAM, 16GB internal storage, microSDHC expansion, 802.11a/b/g/n WiFi, Bluetooth 4.0 (LE), NFC, LTE and CDMA/GSM/UMTS/GPRS radios -- that's right, it's a global device. Not bad for a 140g package, and it's waterproof as well, rated at IPX5. But the question is how well will the 2,020mAh battery last under that super dense LCD and high-end processor? Only time will tell -- even KDDI has yet to finalize this part of the specs. Folks on the KDDI network can grab hold of this powerful phone in early December, with a choice of red, white or black.

Update: HTC confirmed to us that this phablet will use panels supplied by Sharp and JDI.

Dolby spinoff Via Licensing has shone a signal into the night sky and assembled some of the world's biggest telecoms players to form a patent supergroup. AT&T, NTT DoCoMo and Telefonica are some of the names that'll pool their standards-essential LTE patents to prevent getting embroiled in litigation over FRAND licensing. While there are some notableholdoutstotheteam, we suggest company president Roger Ross coax them over by hiring Michael McCuistion to write them a rockin' theme song.

Sidestepping lockscreen codes and fingerprint scanners -- and without any new hardware demands -- KDDI has unveiled a new palm authentication app that takes advantage of the high-resolution camera on its Android smartphones. Scanning in tandem with the flash, we gave it a try on a HTC J, here at CEATEC in Japan. After a brief setup, which involves positioning your hand to fit between some red markers, the phone was soon calibrated to our hands. Then, after locking the device, attempting to unlock it will send you to the palm authentication screen, seen above, where (hopefully) only your mitts will be able to gain access.

The time it takes to check your hand remains a little longer than it would take you to drum in your typical four-digit PIN, but in our brief test, it was able to discriminate between two Engadget editors' hands. Better still, you'll be able to give the app a try yourself tomorrow, when it goes on free trial on Google Play. Until it does, see how it's all meant to work in our hands-on video after the break.

Add another future Sony Xperia model to a rapidly growingpool. The LT25i Tsubasa (not to be confused with the ST25i/Xperia U) has been caught by Tencent in AnTuTu and NenaMark2 tests, seemingly running the same mix of a 1.5GHz Snapdragon S4, a 720p screen and Android 4.0 that we've seen in the upcoming Xperia T (LT30p). So what's different? There's rumors of in-cell touch to keep the display thin and vivid, but even the unverified source isn't certain that it will become a reality. The crew at Xperia Blog also claims that there will be international LTE and HSPA+ models along with China- and Japan-specific editions. Assuming the details are at all consistent with the truth, having the Tsubasa arrive on the scene mostly hints that Sony might be readying a broader speed-up of its roster than we first thought.
